Squeeze-Latch Audio Cassette Case (Vase Mode)

I wouldn't recommend using this with a tape you really care about since it's prone to scratching tape shells! It's not a major concern on a solid color, but it might show up more on a glossy clear shell.  

This started as an experiment to see if I could 3D print a sliding case for a cassette. I thought it might be more useful if the tape locked in place, so I decided to see if I could make a latching design with no moving parts. It took a couple iterations, but here's the final design. Hopefully it's useful to someone!

I've also included two shelled versions NOT for vase mode (for 0.4mm and 0.6mm nozzles), in case you want to print more than one at a time.
